IMPROVEMENT IN WATCH-DIES.

Specification forming part of Letters Patent No. 54,539, dated May 8, 1866.

To all whom it maw concern:

Beit known that I, GEORGE HAs'rINGs, of Waltham, in the county of Middlesex and State of Massachusetts, have made a new and useful invention having reference to Dies for Making Watch 0r Time-Piece Hands; and I do hereby declare the same to befully described in the following specification and represented in the accompanying drawings, of which- Figure l is a top View, Fig. 2 an edge elevation, Fig. 3 a longitudinal section, and Fig. 4 a bottom View, ot' a die made in accordance With my invention.

The said die is specially designed for making the fleur-delis pattern ot' watch-hand, and consists of three pairs, A A B B O C, of steel plates, formed and arranged in a peculiar 1n anner, and united to two connection-plates, D D.

In carrying out my invention, I arrange the plates ot each pair opposite to each other, in manner as represented, and make each ot' the plates which iiank either of the middle plates, A A, with a small projection to extend by the inner end of the plate A, the same being as represented at c and b in Figfl. I also curve the inner end of each of the plates A, and form it with a recess, c, in manner as exhibited in Fig. 1.

Between each part a or b and the inner end of the plate A which is overlapped by such part there is a space, as shown in thedrawings. These spaces, the space d between the two dies A A, and the circular recesses o c constitute that part of the die through which the metal passes during the formation of the ieur-de-lis ofthe hand, the remaining portions cf the hand being formed by the inner edges of the two pairs of dies B B and G C, which are shaped as shown in Fig. l.

Each of the dies A A is dovetailed and fastened into one of a pair of supporting-plates, D D. vThe other dies are secured to the said plates by means ot' screws, and the two supporting-plates are to be connected together by bolts or screws going from one into the other of them.

ln using this die, a plunger or male die having its bottom surface corresponding in shape with the female die formed by the three pairs of plates A A B B O C is employed to force the metal down into such female die. I also employ another plunger, arranged so as to work upward Within the female vdie and expel therefrom a watch hand after having been formed by it.

I claim as my invention- The watch-hand die as made of the three pairs of plates AA B B C C, formed, arranged, and combined substantially as specified.
